Due to the relocation of a magnet power supply, the installation of a buss, and an installation of chokes. and their need for cooling water a redesign of the Low Conductivity Water (LCW) system has been undertaken. This new system required the determination of an optimal pipe diameter for the High Bay pipe as well as the determination of the pressure drop and temperature rise in the buss. Based on numerous calculations it has been determined that the High Bay pipe should be 1 1/2 inch (1.90 O.D. x 1.610 I.D-40S steel). While the pressure drop in the buss was calculated to be 7.699 psi. Based on such a low pressure drop, no need for any additional pumps has presented itself. Finally, the temperature rise in the buss has been determined to be about 29.39 F for the Assembly Hall (route No.1). and 13.93 F for the Collision Hall (route No.2). The purpose of this engineering note is to explain the redesign of the low conductivity water system (LCW) at D-Zero. The areas to be covered include the sizing of the High Bay, the pressure drop and temperature rise in the buss. In addition, I will try to determine if …

This safety assessment (SA) addresses each of the required elements associated with the installation, operation, and removal of a rotary-mode core sampling (RMCS) device in flammable-gas single-shell tanks (SSTs). The RMCS operations are needed in order to retrieve waste samples from SSTs with hard layers of waste for which push-mode sampling is not adequate for sampling. In this SA, potential hazards associated with the proposed action were identified and evaluated systematically. Several potential accident cases that could result in radiological or toxicological gas releases were identified and analyzed and their consequences assessed. Administrative controls, procedures and design changes required to eliminate or reduce the potential of hazards were identified. The accidents were analyzed under nine categories, four of which were burn scenarios. In SSTS, burn accidents result in unacceptable consequences because of a potential dome collapse. The accidents in which an aboveground burn propagates into the dome space were shown to be in the ``beyond extremely unlikely`` frequency category. Given the unknown nature of the gas-release behavior in the SSTS, a number of design changes and administrative controls were implemented to achieve these low frequencies. Likewise, drill string fires and dome space fires were shown to be very low frequency …

This analysis is prepared by the Mined Geologic Disposal System (MGDS) Waste Package Development Department (WPDD) to compare the criticality potential of Westinghouse 17 x 17 mixed oxide (MOX) PWR fuel with the Design Basis spent nuclear fuel (SNF) analyzed previously (Ref. 5.1, 5.2). The basis of comparison will be the conceptual design Multi-Purpose Canister (MPC) PWR waste package concepts. The objectives of this evaluation are to show that the criticality potential of the MOX fuel is equal to or lower than the DBF or, if necessary, indicate what additional measures are required to make it so.

The purpose of this analysis is to define the spatial requirements of the area (pad) for storage of muck removed from the tunnel area during the construction of the Exploratory Studies Facility (ESF). This analysis uses the estimate for the amount of material to be removed and determines the required area of the storage pad. Two different areas, Areas 1 and 2, considered as primarily suitable areas, will be analyzed (see Attachment I). An Optional Muck Storage Area, to be located to the east of the ESF pad, will also be analyzed for available volume, with an option of raising the stockpile of muck to 49 feet (see Attachments II and III).

Currently, the Morgantown Energy Technology Center, is actively investigating alternative hot fuel gas desulfurization sorbents for application to the Integrated Gasification Combined Cycle (IGCC). A sorbent must be highly active towards sulfur at high temperatures and pressure`s, and under varying degrees of reducing atmospheres. Thus, high conversion of the metal oxide and low hydrogen sulfide exit partial pressures. Also, it must regenerate nearly ideally to maintain activity over numerous cycles. Furthermore, regeneration must yield a sulfur product which is economically recoverable directly or indirectly. This cyclic process requires a holistic approach as any one criteria may eliminate a candidate sorbent from further consideration. Over fifty induration campaigns have been conducted among the fifteens Mn-based sorbent formulations. All indurated sorbents has been tested for crush strength and chemical analysis. Also, fifteen sorbent formulations have been tested in a TGA for at least on e induration condition. Subsequently described are the three main groups of formulations tested. They are the MnCO{sub 3} supported with TiO{sub 2} (with or without bentonite), MnCO{sub 3} supported with Al{sub 2}O{sub 3} (with or without porosity enhancers), and MnO{sub 2} ore supported with alundum (with and without bentonite).

The specific goals of the ASTC program were: to pilot and administer a year round program to engage and support ethnic minority and women students to enter the pre-college teaching profession; and to develop the ASTC program across California on all twenty CSU campuses. The initial goal of piloting a year round program to engage and support ethnic or underrepresented science students to enter the teaching profession was put in place at CSUS in the Fall of 1993, with the recruitment of students to enter the program in the Spring of 1993. Three students were selected to enter the program, one male Latino, one female Latina and one Caucasian female. The areas of study of these students was respectively biology, physics and geology. All of the students were within two years or less of completing their degree requirements. During the first semester of the program the authors worked on the portion of the model dealing with student participation in the schools with a mentor teacher. The idea being the students would spend a minimum of six hours a week in the classroom of the mentor teacher working with them and their students. In addition the students were assigned to a …

Each of the twelve Booster Main Magnet Power Supply modules consist of two three-phase, full-wave rectifier bridges in series to provide a 560 VDC maximum output. The harmonic contents of the twelve-pulse ac-dc converter output are multiples of the 60 Hz ac power input, with a predominant 720 Hz signal greater than 14 dB in magnitude above the closest harmonic components at maximum output. The 720 Hz harmonic is typically greater than 20 dB below the 500 VDC output signal under normal operation. Extracting specific harmonics from the rectifier output signal of a 6, 12, or 24 pulse ac-dc converter allows the detection of SCR firing angle errors or complete misfires. A bandpass filter provides the input signal to a frequency-to-voltage converter. Comparing the output of the frequency-to-voltage converter to a reference voltage level provides an indication of the magnitude of the harmonics in the ac-dc converter output signal.

Solar is developing the technologies for a highly efficient, recuperated, Advanced Turbine System (ATS) that is aimed at the dispersed power generation market. With ultra-low-emissions in mind the primary fuel selected for this engine system is natural gas. Although this gas fired ATS (GFATS) will primarily employ natural gas the use of other fuels particular those derived from coal and renewable resources cannot be overlooked. The enabling technologies necessary to direct fire coal in gas turbines were developed during the 1980`s. This Solar development co-sponsored by the US Department of Energy (DOE) resulted in the testing of a full size coal-water-slurry fired combustion system. In parallel with this program the DOE funded the development of integrated gasification combined cycle systems (IGCC). This report describes the limitations of the Solar ATs (recuperated engine) and how these lead to a recommended series of modifications that will allow the use of these alternate fuels. Three approaches have been considered: direct-fired combustion using either a slagging combustor, or a pressurized fluidized bed (PFBC), externally or indirectly fired approaches using pulverized fuel, and external gasification of the fuel with subsequent direct combustion of the secondary fuel. Each of these approaches requires substantial hardware and system …

This Standards/Requirements Identification Document (S/RID) set forth the Environmental Safety and Health (ES&H) standards/requirements for Westinghouse Hanford Company Level Programs, where implementation and compliance is the responsibility of these organizations. These standards/requirements are adequate to ensure the protection of the health and safety of workers, the public, and the environment.

The Department of Energy (DOE), Richland Operations is responsible for ensuring that its contractors` tasks are mission oriented and are completed at the least cost to the DOE. The objective of this audit was to determine whether Richland was effectively managing its groundwater monitoring activities so that unnecessary duplication would not occur. The audit`s objective was accomplished by: reviewing laws and regulations; interviewing DOE and contractor personnel; examining procurement and accounting procedures; reviewing plans, budgets, and actual expenditures; reviewing utilization of the DOE drilling equipment; observing well drilling activities; comparing drilling cost to other DOE sites; analyzing groundwater monitoring activities; and, reviewing and comparing groundwater reports.

The Refrigerant Database is an information system on alternative refrigerants, associated lubricants, and their use in air conditioning and refrigeration. It consolidates and facilitates access to property, compatibility, environmental, safety, application and other information. It provides corresponding information on older refrigerants, to assist manufacturers and those using alternative refrigerants, to make comparisons and determine differences. The underlying purpose is to accelerate phase out of chemical compounds of environmental concern.

The purpose of this report is to summarize results of relevant data (tank farm and laboratory) and analysis related to potential chemical vulnerabilities of the Hanford Site waste tanks. Potential chemical safety vulnerabilities examined include spontaneous runaway reactions, condensed phase waste combustibility, and tank headspace flammability. The major conclusions of the report are the following: Spontaneous runaway reactions are not credible; condensed phase combustion is not likely; and periodic releases of flammable gas can be mitigated by interim stabilization.

Currently, Tanks Farms Transition Projects require personnel to perform a whole body survey with portable survey instrumentation prior to entering an automated counting system capable of performing a whole body survey. This practice is redundant since automated whole body survey devices are, in most cases, more sensitive and are less likely to be used incorrectly than portable instrumentation. Additionally, Article 221.2 of the Hanford Site Radiological Control Manual (HSRCM-1) states ``Monitoring for contamination should be performed using frisking equipment that under laboratory conditions can detect total contamination of at least the values specified in Table 2-2.`` Based on this criteria implementing the use of an automated whole body survey device would save significant time, money and reduce the current crowding and potential loss of contamination control that now occurs during peak times at step off pads. This document describes implementation process for applying PCM-1B instruments to perform personnel release surveys.

Three cores from tank 241-S-107 were received by the 222-S Laboratory and underwent analyses to meet the requirements of the Tank Safety Screening Data Quality Objective and Historical Model Evaluation Data Requirements.

The Groundwater Maps of the Hanford Site, June 1995 is a continuation of a series of reports (see Serkowski et al. 1995) that document the configuration of the water table aquifer beneath the Hanford Site (Figure 1). This series presents the results of the semiannual water level measurement program and the water table maps generated from these measurements. The reports document the changes in the groundwater level at the Hanford Site during the transition from nuclear material production to environmental restoration and remediation. In addition, these reports provide water level data to support the various site characterization and groundwater monitoring programs currently in progress on the Hanford Site. Groundwater Maps of the Hanford Site is prepared for the U.S. Department of Energy by the Hanford Site Operations and Engineering Contractor, Westinghouse Hanford Company (WHC). This document fulfills reporting requirements specified in WHC-CM-7-5, Section 8.0 ``Water Quality`` and described in the environmental monitoring plan for the Hanford Site. (DOE-RL 1993a) This document highlights the three major operations areas (the 100, 200 and 300/1100 Areas) where wastes were discharged to the soil. Each area includes a summary discussion of the data, a well index map, and a contoured map of the water …

A Distributive Process Control system was purchased by Project B-534, 242-A Evaporator/Crystallizer Upgrades. This control system, called the Monitor and Control system (MCS), was installed in the 242-A evaporator located in the 200 East Area. The purpose of the MCS is to monitor and control the Evaporator and monitor a number of alarms and other signals from various Tank Farm facilities. Applications software for the MCS was developed by the Waste Treatment Systems Engineering (WTSE) group of Westinghouse. The standard displays and alarm scheme provide for control and monitoring, but do not directly indicate the signal location or depict the overall process. To do this, WTSE developed a second alarm scheme.

Experiments were performed to study the rates of endocytosis, intracellular routing, and metabolic degradation of radiolabeled monoclonal antibodies targeting tumor-associated antigens on human leukemia and lymphoma cells. An attempt was made to examine in vivo the effects of lysosomotropic amines and thioamides on the retention of radiolabeled monoclonal antibodies by tumor cells. Experiments also examined the impact of newer radioiodination techniques on the metabolic degradation of radioiodinated antibodies, and on the radioimmunoscintigraphy and radioimmunotherapy of neoplasms. The endocytosis, intracellular routing, and degradation of radioimmunoconjugates prepared with I-131, In-111, and Y-90 were compared. The utility of radioimmunoconjugates targeting oncogene products for the radioimmunotherapy and radioimmunoscintigraphy of cancer was investigated.

This BCR compares the Project W-058 Functional Design Criteria with the Project W-058 Preliminary Design Requirements Document,and identifies the differences between the two documents in the mission definition, project requirements, system functions, and interfaces. Impacts these differences have on current project design are also discussed.

The authors have examined the role of the {beta}{sub 1} integrin family of adhesion receptors (VLA) and the extracellular matrix protein fibronectin (FN) in macrophage differentiation of (1) human HL-60 myeloid leukemia cells induced by phorbol 12-myristate 13-acetate (PMA) and (2) human peripheral blood monocytes induced by either PMA or macrophage-colony stimulating factor (M=CSF). Increased VLA and FN gene expression was observed as early as 4 h after PMA treatment of HL-60 cells and PMA- or M-CSF-treatment of monocytes, and it preceded the manifestation of macrophage markers. Treated HL-60 cells and monocytes also released and deposited FN on the surface of the tissue culture dishes. An HL-60 cell variant, HL-525, which is deficient in protein kinase C {beta} and resistant to PMA-induced differentiation, exhibited elevated levels of the VLA antigen but failed to express the FN gene. Incubation of HL-525 cells on dishes precoated with exogenous FN resulted in a macrophage differentiation. The macrophage phenotype induced in HL-60 cells, HL-525 cells, or monocytes was attenuated to various degrees by anti-VLA or anti-FN MAbs or by exogenous RGDS, a VLA-binding motif on FN. The authors suggest that macrophage differentiation is initiated by the activation of protein kinase C, which leads to …
